Not sure if this has anything to do with your changes or not but I can
no longer use Bing imagery. If I select Bing as the background,
Vespucci crashes when I go back to the map. Then I can't even start it
up until I nuke all data to reset the background option back to mapnik
tiles. If it isn't related to your changes, I'm wondering if it might
have to do with problems people were seeing with Bing in JOSM and P2 a
couple of days ago.
